The Flash Season 2: 10 Things That Need To Happen Before The Mid-Season Break

5. Take A Trip To Earth Two

The introduction of Earth Two has been one of the best things about the show this year, really expanding its mythos and increasing the possibilities of what they can do. They can have multiple versions of characters, and use Earth Two to bring some of the more outlandish characters into the fold (looking at you, King Shark). It's worked really well so far, but at some point we're going to need to take a trip there for the majority of an episode, if not the whole one. There's still so much we don't know about it, and a lot of the plot hinges on people from there - Zoom, Jay Garrick, Harry Wells - that it just makes sense for our heroes to go through at some point, and if the end of the mid-season finale was Barry ending up in Earth Two to face off with Zoom or rescue Wells' daughter it would be fantastic way to close out this part of the season.
